NASA and the infinite industry are in agreement : If we need to install a permanent human presence on the moon , we ’ll necessitate to make habit of every native imagination we can — and none are as crucial as body of water ice .
Starpath Roboticsis one of a smattering of startup planning for this future . The inauguration is bet that there will be a thriving securities industry for liquified atomic number 8 ( LOX ) refined from lunar H2O chalk and that harvesting this imagination will be key to humanity ’s enlargement throughout the solar system of rules . LOX is a all-important component of propellant for some vehicles like Eruca vesicaria sativa and spacecraft like lunar landers , and it ’s used as the oxidizer alongside a combustible fuel such as hydrogen , kerosene , or methane .
The companycame out of stealth last Septemberwith an ambitious water - harvesting computer architecture , involve mining rovers , refinery and LOX reposition systems . Starpath wants to launch a demo missionary station “ as promptly as we possibly can , ” CEO Saurav Shroff said in a recent interview . To ensure the ironware will be ready whenever a launching vehicle is available , the caller announce today that it has closed a $ 12 million come round , co - led by 8VC and Fusion Fund , with participation from Day One Ventures , Balerion Space , and Indicator Ventures .
Much of the architecture has remained the same since Starpath primitively unveiled its plan last yr : Essentially , the company wants to use fleets of mining rovers that dig up hundred of tons of lunar poop and retrovert it to self-reliant lunar processing plan that excerpt the water , splits those speck into their component atoms , and then liquifies the oxygen . The entire organization would be powered by a massive solar raiment that ’s being contrive in coaction with infinite solar inauguration Solestial .
There are some changes , however . Shroff tell the 10 - person squad has made improvements on the excavation roamer ironware such that it will take far fewer bird of passage to produce a 1,000 - ton annual harvesting scale ( the company primitively estimated it would take 50 roamer to hit that pace ) . Rover growing also engender a rise with $ 800,000 in NASA subsidization , as part of the space agency’sBreak the Ice challengeto individual diligence . There is still much to develop , let in the solar array and refinery , but the canonic architecture is fundamentally plan out . With that in position , the company ’s been turn its aid to the final fundamental interaction between its ironware and the client ’s vehicle .
Figuring this out means solving a few problems , namely how to transmit the LOX to the vehicle , which could be some distance away . The other problem , of class , is how to actually load the fomite with the intersection .
For the first issue , Shroff suppose the company is simply configuring its scandal - hauling rover to carry pressurized cryogenic propellent tanks instead . For the second , while he declined to go into particular , he said the roamer would be fit with a specialized refueling instrument , that in all likelihood will be project on a client - by - client basis .

As of aright now , there are few prospective customer for lunar liquid oxygen , but those that are planning moon missions could prove to be prolific buyers . Both SpaceX and Blue Origin have contracts with NASA to land on the lunation before the end of the decade ; Shroff estimates that Starship would consume around 100 - 300 tons of oxygen on the synodic month per flight of steps , and something like Blue Origin ’s Blue Moon would go through tens of tons of oxygen per flight .
Given that Starpath is calculate to produce around 1,000 tons of LOX per twelvemonth , unconstipated Starship flights to and from the lunar control surface alone could be enough demand to support this yield capacity . At that pace , Shroff says , any hustler would be capable to vanish a vehicle to the lunar month and trust they will be able to refuel it while they ’re there .
By the final stage of this class , the company is place to carry on an ending - to - end , full - scale leaf presentation of its system in a false lunar environment , which they ’ll build out at their 12,000 - straight - foot premiss . After that , they ’ll embark on a serial publication of test campaigns before set in motion their first demonstration foreign mission . The goal for that first mission is to harvest the combining weight of around 100 ton of fluid oxygen per year . It ’s incredibly challenging : Scientists have confirmed that urine ice is on the moon , but no government or company has ever harvested it , rent alone refined it in situ .
Starpath is currently at 10 full - time employee , and the raw capital will primarily go toward double or even tripling that number at a dissipated rate . The payoff for getting this technology online could be enormous , the troupe is betting , with the moon just the first stepping stone to expansion through the solar organization . Starpath already has its eye on explicate processing plans and rover harvest home fleets for Mars , which would be augmented from their lunar counterparts , to exchange CO2 in the Martian atmosphere into methane .
“ aliveness can be multiplanetary in a very short menstruation of fourth dimension , ” Shroff order . “ If you make 1,000 tons of smooth atomic number 8 on the moonlight , your track to pretend a million - individual urban center on Mars is hard , but it ’s now possible . ”
